水下传感器网络中位置隐私保护方法的关键问题研究

水下传感器网络在海洋资源勘测、环境监测和安全保障等方面具有广阔的应用前景。位置隐私保护是水下传感器网络的核心研究内容。作为网络安全的一个研究热点，隐私保护在保护节点位置，延长网络安全期等方面发挥着巨大作用。传统的位置隐私保护方法往往需要消耗较多的能量、通信量、计算量，难以适用于资源受限的水下传感器网络。因此，本项目将在我们前期研究的基础上对水下传感器网络中位置隐私保护方法进行系统的研究，主要研究内容包括：（1）在网络模型方面，进行基于埃克曼漂流理论的水下传感器网络全覆盖建模研究；（2）在位置隐私保护方面，进行基于支持向量机的水下传感器网络隐私保护路由路径构建研究；（3）在协议优化方面，进行基于可靠性分析的水下传感器网络隐私保护路由路径优化研究。本课题的研究对探索水下传感器网络安全技术及应用具有重要的理论价值和实际意义。

Abstract: Underwater wireless sensor networks have a wide range of application in ocean resources investigation, environmental monitoring, and security. Location privacy protection, which is a hot research topic in security of underwater wireless sensor networks, plays an essential role in protecting sensor location, prolonging the safety time of the network and so on. Traditional location privacy protection methods in wireless sensor networks usually cost too much energy on communication and computing, which cannot be directly applied into energy restricted underwater wireless sensor networks. Thereby, based on previous works on underwater, we perform a systematic study on location privacy in underwater wireless sensor networks. The main researches contain three aspects: (1) research on building a full coverage underwater sensor network model based on Ekman drift current theory; (2) research on constructing routing scheme based on support vector machine; (3) research on optimizing the routing path based on reliability analysis. This research will provide both theorical and practical value for exploring underwater security technique.
